Thank you all for the great advice. This is why I love this forum so much.
@bibenu and @Tlsckr Those both look perfect. Not sure if the retrokit ships to the US though. May give the Blockas a spin if nothing else works.
@Octagonist Awesome idea. Works like 90% great. A few quirks with the DT of course, but isn’t that always the case. I can record trigs on the DT only with the KSP set to DT’s auto channel. My Eurorack channels only fire if the KSP is set to DT auto and I press two keys on the KSP simultaneously ( 
). Etc.
@echoicMalady 
That looks like a cleaner version of my idea. It looks like I’m purchasing a merge box. Thanks!
@PeterHanes I have a Hydrasynth desktop, DT, 1/2 of a Korg Monologue, beginning of eurorack (2 midi channels via Niftycase), Yamaha Clavinova digital piano, and a new Vermona Perfourmer. Also have Empress Echosystem and Reverb pedals that I’m curious about sending cc trigs to via the DT. Also a Lyra-8 (no midi). Everything was swimming along beautifully until I got the Perfourmer. It is so much fun to play with the KSP, but it uses up all 4 tracks.
